derivative_21_1.gif.

 

derivative_22

Find a formula for the derivative with respect to x for the function. (Treat a, b, and c as constants.)
derivative_22_1.gif.

 

derivative_23

Find a formula for the derivative with respect to x for the function. (Treat a, b, and c as constants.)
derivative_23_1.gif.

 

derivative_24

Find a formula for the derivative with respect to x for the function. (Treat a, b, and c as constants.)
derivative_24_1.gif.

 

derivative_25

If derivative_25_1.gif, where derivative_25_2.gif is a constant and derivative_25_3.gif is a function of derivative_25_4.gif , then use the definition of the derivative to prove that derivative_25_5.gif .

 

derivative_26

Write an expression for derivative_26_1.gif for the function derivative_26_2.gif. ( derivative_26_3.gif ). Then use the definition of the derivative to find derivative_26_4.gif.

 

derivative_27

Using the definition of the derivative, show that, if derivative_27_1.gif , then derivative_27_2.gif.

 

derivative_28

Find the values of derivative_28_1.gif where the slope of the curve derivative_28_2.gif is equal to 3.

 

derivative_29

For what values of derivative_29_1.gif is the line derivative_29_2.gif tangent to the curve derivative_29_3.gif?

 

derivative_30

Newton's method provides an iterative method for estimating the x-intercept of complicated functions. The goal of the method is to find derivative_30_1.gif such that derivative_30_2.gif . First, make a guess ( derivative_30_3.gif ) that is reasonably close to the true value of derivative_30_4.gif . Then calculate a better guess according to the formula derivative_30_5.gif . The method can be repeated to yield a still better guess, derivative_30_6.gif . Keep going until you are satisfied that the result is close enough to the true answer. Now, use Newton's method to estimate the cube root of 7. Start with derivative_30_7.gif , and find the x-intercept of the function derivative_30_8.gif . Perform a total of 3 iterations and compare with a calculator value.
